pythont编写atm

好的，以下是一个简单的 Python ATM 程序：

class ATM:
    def __init__(self, card_number, pin):
        self.card_number = card_number
        self.pin = pin

    def check_balance(self):
        print("Your balance is $1000")

    def withdraw(self, amount):
        new_amount = 1000 - amount
        print("You have withdrawn "+str(amount) +". Your remaining balance is "+ str(new_amount))

def main():
    card_number = input("Insert your card number: ")
    pin = input("Enter your pin: ")

    new_user = ATM(card_number, pin)

    print("What do you want to do?")
    print("1. Check balance")
    print("2. Withdraw")

    activity = int(input("Enter activity number: "))

    if(activity == 1):
        new_user.check_balance()
    elif(activity == 2):
        amount = int(input("Enter the amount to withdraw: "))
        new_user.withdraw(amount)
    else:
        print("Enter a valid number")

main()

这个程序使用类来创建一个 ATM 对象，然后根据用户输入的选项执行不同的操作。在这个程序中，我们只是简单地检查余额和提取现金。你可以根据你自己的需求来扩展这个程序。
